WILLIAM F. GBBS, OF NEW' YORK, Y.

INTERNAL-COMBUSTION ENGINE To all whom t may concern.'

Be it known that I, WILLIAM Grs, a citizen of the United States, residing iat NewYork, in the county of New York and State of New York, have invented certain new land useful Improvements in Internal- Combustion Engines, of which the following specification. i

The principal object of the present inven tion is toA improve the-construction and opf` eration ofthe valves, lwhereby they are posi* tively operated, Va very rapid opening and closing obtained, a very large valve area obtained, compact and cylindrical clearance space retained without'the necessity of distorting this cylindricallshape by theV introduction of pockets, etc., all of which factors have a direct relation tothe efficiency of the internal Vcombustion engine. l The valves furthermorebythis arrangement are not in Contact withthe piston Vandare capable of easy removal and application as an vassemn ybled unit, andspring `piston rings and other y packing may be introduced between each sliding surface between which surfaces the gases yof combustion or compression would have a tendency to escape.

Theinvention will/be Lclaimed at the end hereof but will first be described in connection with' the embodiment oflit` chosen for illustration in kthe accompanying drawings in whichV`v j f 'y kFigure 1, is a side vieu/,partlyV in section andvpartly in elevation, of an engine or mo- `torfembodying features ofthe invention.

Fig. 2, is a sectional view taken, through one of the cylinders in a plane at right angles to the plane kof Fig. 1, and Fig. 3, is a partial plan view. i f 'p n v The; cylinders and the valve gearv therefor are alike and a description lof one will suffice. In the drawings 1', `is a cylinder having exhaust ports or openings 2, .and having fat, as shown in the drawings its upper end `a clearag ncey space into which the piston vdoes not travel. As shown the exhaust ports 2,.V

are'elongated and extend well around the cylinder. l i

3, are channels for water cooling.

4, are openings for spark plugs. The cylinder head 5, is provided with a tubular admission projection 6,' between which and the end partv of the cylinder wall there is an 'annular space. The cylinder head with the parts which it carries is re- Y Specification of Letters Patent.

pet valve 8, coperates with a seat on the inner face of the projection 6, to Vcontrol the admission, and the stem 9., of this valve works `through a spiderlO, formed in the extension.v This spider 10, also coperates with the spring 11, of thepuppet valve.

`The puppet valve is opened againstV theY force of its spring 11, by aic'entra'lly pivoted arm 15', one end of which operates, as shown,

.through the intervention of an adjusting screw 16, on the end of the stem of the puppetvalve and the other `end of which is operated upon a cam or eccentric' 17, on the shaft 14. The sleeve valve 12, is provided withupwardly extending ears 1S and 19.

One endvof` the centrally pivoted arm 20, is

Vconnect-cd.with one ear 18, and one end of the centrally pivoted varm 21, is connected with theother earr19, `and these arms 2O and 21, are keyed to and made part of the same pivot shaft, and these' arms, 20 and 21, are operated upon by oppositely disposed cams or eccentrics 22 and 23, on the shaft 14, so

that the sleeve valve 12, is positively oper- 1 .atedv in each direction.y The puppet valve is positively operated in one direction to open it and is spring operated to close it.

24, are supports forthe pivot shaft ofthe valveoperating levers 20 and 21, which Vare keyed to or'A made integral with said shaft. The valve operating lever'l is not keyed to said shaft but is Vfree to'oscillate thereon.

`25, isa hood. By removing the fasteningsj?, the cylinder headfbo'th valves and the valve levers are detached from the cylinder so that neither the cylinder nor piston are disturbed while the various parts are readily accessible for cleaning or for repairs.V The valves and levers being thus removable as an assembled unit by removing the'fastenings 7. The movements of the valves are of course timed to accord with ordinary practice. Y

It will be obvious to those skilled in the art to ivhichmy invention relates that modiications may be made in details of construcmay require, but
